Dan + Shay were part of a major country lineup during the eighth annual CMA Country Christmas program held at Nashville's Grand Ole Opry. The two-hour broadcast on Nov. 27 featured the duo singing a powerful rendition of the holiday classic "Do You Hear What I Hear?"

The duo's beautiful harmonies were highlighted throughout their nearly four-minute performance. Backed by strings and additional vocalists, Shay Mooney's striking falsetto was complemented by Dan Smyers' assistance. On a stage decorated with Christmas lights, Dan + Shay brought the holiday season to Music City with their powerful performance.
